Heat Burst
In meteorology, a heat burst is a rare atmospheric phenomenon characterized by a sudden, localized increase in air temperature near the Earth's surface. Heat bursts typically occur during night-time and are associated with decaying thunderstorms. They are also characterized by extremely dry air and are sometimes associated with very strong, even damaging, winds. Although the phenomenon is not fully understood, the event is thought to occur when rain evaporates (virga) into a parcel of cold, dry air high in the atmosphere, making the air denser than its surroundings. The parcel descends rapidly, warming due to compression, overshoots its equilibrium level, and reaches the surface, similar to a downburst. Recorded temperatures during heat bursts have reached well above , sometimes rising by or more within only a few minutes. Characteristics In general, heat bursts occur during the late spring and summer seasons. During these times, air-mass thunderstorms tend to generate due to ...

Meteorology
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.

Convection
Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow. Convective flow may be transient (such as when a multiphase mixture of oil and water separates) or steady state (see Convection cell). The convection may be due to gravitational, electromagnetic or fictitious body forces. Heat transfer by natural convection plays a role in the structure of Earth's atmosphere, its oceans, and its mantle. Discrete convective cells in the atmosphere can be identified by clouds, with stronger convection resulting in thunderstorms. Natural convection also plays a role in stellar physics. Convection is often categorised or d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donna Nook
Donna Nook is a point on the low-lying coast of north Lincolnshire, England, north of the village of North Somercotes and south of Grimsby. The area, a salt marsh, is used by a number of Royal Air Force stations in Lincolnshire for bombing practice and shares its name with RAF Donna Nook. The site was also made available to commercial organisations such as BMARC for firing tests. Wildlife seems to have become accustomed to regular aircraft bombing according to The Wildlife Trust. The name is popularly supposed to be derived from a ship called ''The Donna'', part of the Spanish Armada, which sank off the Nook (a small headland) in 1588. A coastal strip stretching from Saltfleet in the south, to Somercotes Haven in the north, is managed by the Lincolnshire Wildlife Trust as a nature reserve. It is part of the land owned by the Ministry of Defence and used as a bombing range. The grey seal The grey seal (''Halichoerus grypus'') is found on both shores of the North Atlantic ...

Friona, Texas
Friona is a city in Parmer County, Texas, United States. The population was 4,123 at the 2010 census. Friona was established as a small community in 1898 by XIT Ranch, originally called Frio, which is also the word for "cold" in Spanish. The community served as a shipping point for the Pecos and Northern Texas Railroads. In 1906, The George G. Wright Land CO. chose the community for a colonization project, promising settlers of fertile soil, and a healthful climate. The community then became known as Friona after the opening of a post office in March 16, 1907 and started to construct various buildings, which were a hotel, livery stable and a bank. Soon after, the first church in Friona was constructed, and then in the following year of 1908 a school. In 2007, the Texas State Legislature declared Friona the "Cheeseburger Capital of Texas". The city began holding the "Cheeseburger Cook-Off and Festival" in 2006. Aside from this annual event, only three fast-food locations sell chee ...

High Plains (United States)
The High Plains are a subregion of the Great Plains, mainly in the Western United States, but also partly in the Midwest states of Nebraska, Kansas, and South Dakota, generally encompassing the western part of the Great Plains before the region reaches the Rocky Mountains. The High Plains are located in eastern Montana, southeastern Wyoming, southwestern South Dakota, western Nebraska, eastern Colorado, western Kansas, eastern New Mexico. The southern region of the Western High Plains ecology region contains the geological formation known as Llano Estacado which can be seen from a short distance or on satellite maps. From east to west, the High Plains rise in elevation from around . Name The term "Great Plains", for the region west of about the 96th or 98th meridian and east of the Rocky Mountains, was not generally used before the early 20th century.

Dry Line
A dry line (also called a dew point line, or Marfa front, after Marfa, Texas) is a line across a continent that separates moist air and dry air. One of the most prominent examples of such a separation occurs in central North America, especially Texas, Oklahoma, and Kansas, where the moist air from the Gulf of Mexico meets dry air from the desert south-western states. The dry line is an important factor in severe weather frequency in the Great Plains of North America. It typically lies north-south across the High Plains states in the warm sector of an extratropical cyclone and stretches into the Canadian Prairies during the spring and early summer. The dry line is also important for severe convective storms in other regions of the world, such as northern India. In general, thunderstorms and other forms of severe weather occur on the moist side of the dryline. Characteristics Near the surface, warm dry air is denser than warm moist air of lesser or similar temperature, and thus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
